Základní info
The Enterprise JavaBeans 3.0 Technology Update Workshop for Version 2.x Developers course provides hands on EJB 3.0 application development workshop for experienced EJB 2.x developers. This course uses an online auction scenario to demonstrate how to leverage container-managed services with session and message beans, and entity classes to resolve the real-world problems presented by an electronic commerce application. The emphasis of this course is on providing practical EJB technology coding experience, while also covering some designs and best practices used to solve transaction, messaging, and security issues.The course features the Java Platform, Enterprise Edition 5 (Java EE 5) technology, and uses the Java EE 5 SDK. The students perform the course lab exercises using the NetBeans Integrated Development Environment (IDE).Students who can benefit from this course:EJB version 2.x technology business component developers who want to develop EJB technology applications using EJB version 3.0
